Analysis of Genetic Differences in fatty Acids and Oil Contents among Brassica juncea (Linn.) Czern & Coss Genotypes | Chapter 11 | Research Developments in Science and Technology Vol. 1

 The experiment was designed to determine erraticism among 188 Indian mustard genotypes based on various biochemical characteristics such as palmitic, oleic, linoleic, linolenic, and erucic acids, as well as oil composition.

Experiment was carried out at Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, India, Department of Genetics and Plant Breeding, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Rajmata Vijayaraje Scindia Krishi Vishwa

The presence of a significant amount of variation across selected Indian mustard genotypes was determined by analysis of variance, implying improved prospects for their improvement. Oleic acid has the highest genotypic and phenotypic coefficient of variation, followed by erucic and palmitic acids. Heritability and genetic advancement were determined by erucic, oleic, palmitic, linoleic, and linolenic acids. Erucic acid has a strong negative association with palmitic, oleic, linoleic, and linolenic acids. Palmitic acid had the most positive direct effect on erucic acid in both genotypic and phenotypic path coefficient studies, while linoleic, oleic, linolenic acids, and oil content had the highest negative direct effect on erucic acid. The genotypes were clustered into eighteen different groups using genetic deviation and Euclidean distance clustering. Erucic acid was found to be low in 9 genotypes, moderate in 57 genotypes, and higher in 122 genotypes when all biochemical strictures were examined. During a group analysis of qualitative indicators, a severe inter cluster gap between cluster 18 (Karishma) and cluster 12 was discovered (Maya). As a result, these genotypes could be used as parentages in Indian mustard breeding to improve a variety of qualitative indices.
